Exercise-responsive microRNA networks and extracellular vesicle-mediated microRNA signaling in breast cancer: linking tumor signaling, systemic crosstalk, and clinical relevance.
Breast cancer is increasingly recognized as a systemic disease shaped by dynamic interactions between tumor-intrinsic signaling and host physiology. MicroRNAs (miRNAs), as post-transcriptional regulators, extend beyond canonical gene silencing to coordinate oncogenic pathways, tumor microenvironment remodeling, and inter-organ communication. In parallel, exercise has emerged as a systemic modulator capable of influencing immune, metabolic, and circulatory processes relevant to tumor progression. …
